Specification of Letters Patent.

Patented July 20, 1915.

Application filed January 8, 1912. Serial No. 669,911.

One of the objects of my invention is toprovide a machine adapted to divide'valuable mastic material, such as gold paint and the like, and deposit it in small, admeasured and equal quantities on successively resented receiving surfaces, such as g ass palettes or the like.

Such machines, therefore, must be capable of handling the peculiarly sticky material, and on account of the intrinsic value of such material it must operate with the greatest precision that the distribution of quantity and value shall be uniform and unvarying.

In the drawings, which form. a part of this application; Figure 1 is a side elevation of the machine; Fig. 2 is an end elevation; Fig. 3 is a central vertical section; and, Fig.

.4 is a broken away section taken on line 4-4 of Fig. 3. p

' In all ofthe views the same reference characters indicate similar parts.

Supported upon a housing comprising vertical side members 5 and 6, a base member 7, and an upper cross member 8, is, secured a materials reservoir 9. The reservoir is provided with a discharge opening 10 which communicates with a similar opening 11 made in the cross piece 8 of the housing; To the bottom of the part 8 and coaxially arranged with the opening 11 is a conduit or pipe 12 which extends to a point just a little above the base plate 7. The opening 11 is flanked by a receptacle or cylinder 13 which is located at substantially right angles to the said opening. Asa matter of fact the opening 11 is completed through the cylinder. Immediately above the cylinder 13, the valve 14, which is shown in Fig. 3 as being open, permits free passage of material from the reservoir 9 to the cylinder 13. A similar valve, 15, is immediately below the cylinder 13 and the openin 11 and is shown closed, thereby cutting 0 communication between the cylinder 13 and=1the pipe or conduit 12;

I tive seats by nuts 16 and 17.

yieldingly tends other means may be pose, but I prefer the use of a weight and a For purposes of better mechanical strueture I'prefer to taper the valves, as shown in Fig. 4, and to secure them in their respec- The valves are geared together by gear wheels 18 and 19, so that when motion is communicated to the one valve motion in the opposite direction is communicated by the train of gears to the other valve. The valves are adapted to be oscillated by means of the connecting rod 20.

Qn the shaft 21 issecured a pulley 22 which communicates by a belt 23 with the source of power for the purpose of driving the machine. A gear pinion 24 is also secured to the shaft 21 and has geared relation with the gear wheel 25 that is secured to the shaft 26. A cam 27 is secured to the shaft 26 and is adapted to be rotated thereby.

An arm 28 is pivoted to'the housing, as at 29, and is provided with a spring 30 which to hold the arm 28 in its outward position, as shown in Fig. 3. The arm 28 is connected to a piston 29, as by slotand-pin connection 30, and on its lower end is carried roller 31, which is retained in the cam race 32. It will be observed that the cam race, 32, is opened between the points 33 and 34 for a purpose to be hereafter described.

A guide rod 36, for the arm 28, has reciprocating bearing in brackets 37 and 38. The

object of this rod is to hold the roller 31 in i ing a'closed race-way 40, shown in dotted lines in Fig. 1. The arm 20 is provided with or plunger, 29

a roller 41 which is confined within the.

closed race-way 40 of the cam 39. 'By this means the valves are oscillated.

A piston 42 is connected within the cylinder of the reservoir 9 and is urged downwardly, as by .a weight 43, which is connected thereto by means of the rod 44. By

this means a constant and suflicient pressure is exerted upon the contents of the reservoir to cause the material therein to flow readily therefrom when the aperturelO is opened. Of course a spring, pneumatic pressure, or

employed for this purpiston 42' whereby the walls of the receptacle arecleared of the material so as to clean the reservoir as the contents thereof is being discharged. 7 I

As" heretofore stated, the particular exemplification illustrated is designed for depositing small quantities of gold paintupon palettes of vitreous material, such as glass plates, and to this end,'1 have constructed a @v movable platform 45, hinged at one side to the base 7 as at 4:6, for holding the palettes t7 durin the time that the material is being deposite thereon. The plate, or palette, 47 may be'fed to the platform 45, from the stack 48, and after deposit'has been made upon ered,'so that the plate may slide out of position on the platform and then, after restore,-

tion of the platform, another plate may be 2e incline on to the restored platform.

At each revolution ofthe wheel the f valves 14 and 15 will be alternately closed and opened by operation of, the cam 39, and

25 the piston will make one complete excursion by operation-of the cam 37.

When the valve 14 is opened, as shownin Fig. 3, the plastic material contained in the reservoir 9 will be forced into the cylinder 13 i so at the time when the piston 29 is returning to its retracted position, the operation of the piston tending to create a vacuum in the cylinder 13 and, therefore, the material is there" by more readily forced into the cylinder'and completely fills it. While taking place the valve 15 is j as for that reason.
